Macy, the distance from the firewall to the front of the cowl is about 5 inches (it ranges from 4-7/8 to 5-1/16, since the firewall is angled for right thrust). That means the firewall is a little over 1.5 inches too long for the FG60R3. I will take this over to the other thread on the Yak, since this one is about the engine... we can discuss it further, over there.
